Example: The GIA Core helped researchers to digitize the Marcellus Shale area in Pennsylvania and New York, geocode the mine shafts/wells, and identify the school districts that have more than 50 percent of the district’s geographical area in the Marcellus Shale. Other examples of basic services include the construction of two-level hierarchical dataset linking for example individual-level information to census tract-level social, built, and physical environment variables (e.g., presence of toxic release inventory sites and violent crime rates).
